I would like to convert my V belt setup to serpentine system without having to pay for a expensive March setup. This Ebay sale says its for 3 bolt heads. Is it talking about the 3 bolt valve cover style found on the TBI engines? I dont have that so I dont think that would work. I know I saw a post on here where someone took a setup off of a 89-92 Camaro. Either way, if this ebay sale wont work, what donor vehicles should I be looking for for a serpentine setup?
I think the power steering pump might be a issue as well as the water pump. I would like to figure out what to look for.

3 bolt valve covers were only V6. They mean 3 accessory bolt holes. Do you have AC and A.I.R.?
-
I do not have A/C or AIR. All I would need is crank, alt, water pump and P/S. I just looked at a picture I saved of the camaro setup I was talking about and he has a AIR delete pulley. That would work for me, but I would rather have my alt stay on the passenger side.

I tried to get mine off a 91 4.3 blazer, but I decided to get the kit from gm performance parts. No a/c made it a little cleaner for me with just the pulley instead of the compressor w/o air.
-
layne, when you got the kit from GMPP, what year and model did you reference? or did you piece it together?
-
got it from jegs... http://www.jegs.com/i/GM+Performance/809/12497697/10002/-1

Just take a sawzall and cut off the part of the bracket you don't need or find a non AC setup/
-
I have been seeing serpentine belt systems on TBI motors, will it all bolt on? Can I use the system as long as its a small block?
-
yup, sure can might need a reverse water pump
-
One of the guys at work said to look for a early 90's van, thats what he used on his setup with the delete pulley
-

As long as I buy a new water pump for the TBI vehicle I took the setup off of, I should be good? Ive been looking at all the serpentine setups I saw and all the water pumps were CCW, unlike the one on my truck which is CW.

Was it a delete pulley for AC or the AIR?
-
Its for the ac delete, gotta say it looked nice and clean so i guess i'll be heading to the junkyard sunday ;D
-
I was at the north SJ site and there were a few vans there. PITA to get to the front of the engine though...
-
Keep it clasic 8) stay with v belt
-
Yo Beastie i was at the south yard and saw a early 90's chevy van (only one) with the set up your looking for i didnt have enough time for me but you might be interested in picking it up
-

There is nothing wrong with my V belt system, but I like to be different...I mean, look at the color of my truck...
-
The vans got the crappy stamped steel brackets, find a 87 up caprice or 4.3 V6 truck , they got the nice aluminum brackets.

Make sure you get the crank pulley and the WP pulley from the same car or truck you get yours from, My engine had a van system on it and when i went to install the belt, It was offset different, lucky I still had the Caprice pulley.
-
Thanks Jim. When I do get a serpentine setup, Ill probably get everything off the engine and then determine later what I need new parts for. It is my understanding that all engines that have a serpentine setup have a reverse rotation water pump?
-
Yes due to the way the belt is wrapped around the pulley makes it turn opposite of the way it does with a v belt.
-
Are there any problems with hooking up the power steering pump? Should I use the stock pump or the pump from the serpentine kit?
-
yea use the serp P/S pump and just install your old return line, and since yours is a 79 you will need to use your pressure line too, just swap it out from the back of the pump.
-
OK cool, I wasnt sure if it would thread back in or not.

Here's pic for your question about the 3-hole heads
(http://www.crossroadsspeedequip.com/images/engines_for_sale/chevy_350.jpg)
Look at the front end of the heads for the 3 holes in each one. As long as your heads have 3 holes in the front end where the accessories bolt up, the setup will work from any other sb with the 3 holes and 4.3L V6's. I think it was only 69 and older engines that didn't have the holes
-
78, thanks. I wasnt too sure on it and didnt want to put all the effort in pulling everything and then have to return it to the junk yard or loose money on Ebay.
